Abstract
BACKGROUND Childhood myelodysplastic neoplasm (cMDS) often raises concerns about an underlying germline predisposition, and its verification is necessary to guide therapeutic choice and allow family counseling. Here, we report a novel constitutional t(3;8)(p26;q21) in a child with MDS, inherited from the father, the ANKRD26 and SRP72 variants from the maternal origin, and the acquisition of molecular alterations during MDS evolution. CASE PRESENTATION A 4-year-old girl showed repeated infections and severe neutropenia. Bone marrow presented hypocellularity with dysplastic features. The patient had a t(3;8)(p26;q21)c identified by G-banding and FISH analysis. The family nucleus investigation identified the paternal origin of the chromosomal translocation. The NGS study identified ANKRD26 and SRP72 variants of maternal origin. CGH-array analysis detected alterations in PRSS3P2 and KANSL genes. Immunohistochemistry showed abnormal p53 expression during the MDS evolution. CONCLUSION This study shows for the first time, cytogenetic and genomic abnormalities inherited from the father and mother, respectively, and their clinical implications. It also shows the importance of investigating patients with constitutional cytogenetic alterations and/or germline variants to provide information to their family nucleus for genetic counseling and understanding of the pathogenesis of childhood MDS.

Abstract
Evaluation of expression profile in autism spectrum disorder (ASD) patients is an important approach to understand possible similar functional consequences that may underlie disease pathophysiology regardless of its genetic heterogeneity. Induced pluripotent stem cell (iPSC)-derived neuronal models have been useful to explore this question, but larger cohorts and different ASD endophenotypes still need to be investigated. Moreover, whether changes seen in this in vitro model reflect previous findings in ASD postmortem brains and how consistent they are across the studies remain underexplored questions. We examined the transcriptome of iPSC-derived neuronal cells from a normocephalic ASD cohort composed mostly of high-functioning individuals and from non-ASD individuals. ASD patients presented expression dysregulation of a module of co-expressed genes involved in protein synthesis in neuronal progenitor cells (NPC), and a module of genes related to synapse/neurotransmission and a module related to translation in neurons. Proteomic analysis in NPC revealed potential molecular links between the modules dysregulated in NPC and in neurons. Remarkably, the comparison of our results to a series of transcriptome studies revealed that the module related to synapse has been consistently found as upregulated in iPSC-derived neurons-which has an expression profile more closely related to fetal brain-while downregulated in postmortem brain tissue, indicating a reliable association of this network to the disease and suggesting that its dysregulation might occur in different directions across development in ASD individuals. Therefore, the expression pattern of this network might be used as biomarker for ASD and should be experimentally explored as a therapeutic target.

Abstract
To identify the risk factors and attributable mortality associated with superinfections in febrile neutropenic patients with hematologic malignancies, we prospectively evaluated 333 episodes of fever and neutropenia by means of univariate and multivariate analyses. Superinfection was defined as any infection either occurring during antibiotic therapy or developing within 1 week after discontinuation of antibiotic therapy. Of 333 episodes, 46 (13.8%) were defined as superinfection; these episodes occurred in 46 patients. The risk factors for superinfection in the multivariate analysis were longer duration of profound neutropenia (P < .0001), lack of use of quinolones as prophylaxis (P < .0001), presence of a central venous catheter (P = .02), and persistence of fever after 3 days of antibiotic therapy (P = .02). The crude mortality rate among patients with superinfection was 48%, and the attributable mortality rate was 24% (95% confidence interval, 3%-45%). Identifying risk factors for superinfections in neutropenic patients might allow clinical practices to reduce the negative impact of this complication.

Abstract
In this paper we report a eight-year prospective study designed to further characterize incidence, epidemiology, specific syndromes, treatment and prognosis associated with fungal infections in neutropenic patients. During the study period 30 fungal infections were diagnosed in 30 patients among 313 episodes of fever and neutropenia (10%). There were 15 cases of candidiasis, 5 pulmonary aspergillosis, 3 sinusitis by Aspergillus fumigatus, 5 infections by Fusarium sp., one infection by Trichosporon sp., and one infection due to Rhodotorula rubra. Blood cultures were positive in 18 cases (60%). The predisposing factors for fungal infection in multivariate analysis were the presence of central venous catheter (p < 0.001), longer duration of profound (< 100/mm3) neutropenia (p < 0.001), the use of corticosteroids (p < 0.001), gram-positive bacteremia (p = 0.002) and younger age (p = 0.03). In multivariate analysis only recovery of the neutropenia (p < 0.001) was associated with good prognosis whereas the diagnosis of infection by Fusarium sp. (p = 0.006) was strongly associated with a poor outcome. The death rate was 43%. There was no statistically significant difference in the death rate between patients who did receive (52%) or did not receive (50%) antifungal treatment. Identifying patients at risk, specific syndromes and prognostic factors may help to reduce the high mortality associated with disseminated fungal infections in neutropenic patients.

Abstract
PURPOSE To analyse the evolution of 8 cases of Chagas' disease after a microepidemy of 17 cases which occurred in Teotonia-RS-in 1965 and to discuss the importance of oral contamination in Chagas' disease. METHODS All 8 patients are followed at the IC/FUC-RS-Brazil since 1980. Clinical examinations, blood tests, ECG, Cx-Ray and Echo were made in 1991. RESULTS None of the eight cases presented any sign of chronic Chagas' disease manifestation. The blood tests, ECG, Cx-Ray and Echo were normals. Only one case showed a immunofluorescence of 1/20. CONCLUSION 1) The follow-up after 25 years in all the 8 cases did not show clinical alterations or any chronic manifestation of Chagas' disease. All the tests performed had normal results; 2) the oral transmission must be considered definitive in Chagas' disease.
